Sprint has posted the financial results of the fourth quarter of 2012, and things are looking rather good on the whole for the wireless carrier. Launching their 4G LTE network halfway through the year, the company now boasts a sizable 3 million connections to the service. Overall, Sprint added 401,000 new post-paid subscribers. Net additions were up 18 percent year-over-year.

Revenues for the quarter were up to $9 billion, while the total for the year came to $35.3 billion. The company still posted an annual operating loss of $1.8 billion, however.

For 2012, Sprint moved almost 20 million smartphones, accounting for 89 percent of postpaid handset sales. The report cites yearly iPhone sales of more than 6.6 million. Some quick math would indicate around 13 million Android phones sold, give or take a little when factoring in other smartphone platforms.

Sprint is expected to complete a deal later this year that will see Japan’s SoftBank take over as the majority owner of the company.
